Description

technical field [0001] The application relates to the field of cosmetics, in particular, to an external additive and its application, and an external skin product. Background technique [0002] The skin is the largest tissue in the integumentary system consisting of many epithelial tissues that protect the muscles and organs in the body, and plays an important role in protecting the interior of the body from the external environment to maintain homeostasis. [0003] Skin (skin) is composed of epidermis, dermis and subcutaneous tissue. The epidermis, the outermost layer of the skin, is composed of stratified squamous epithelium and functions as a protective barrier for the body from the external environment. The epidermis is divided into stratum corneum, stratum lucidum, stratum granularosum, stratum spinosum and stratum basale from outside to inside. The dermis is the layer between the epidermis and subcutaneous tissue (subcutaneous tissue), divided into papillary dermis a...

Problems solved by technology

However, when retinol is used in a high concentration, it causes skin irritation, skin pigmentation occurs when exposed to ultraviolet rays, and there are stability problems because it is easily oxidized by oxygen in the air, heat, and light, etc.

[0008] Ascorbic acid is easily oxidized by external environments such as air, moisture, and high temperature, so the activity is greatly reduced, thereby reducing the degree of wrinkle improvement, and there is a problem of causing discoloration and odor of the preparation

[0009] In addition, α-hydroxy acids are also disclosed as anti-wrinkle agents, but there are problems in product safety along with skin-irritating side effects such as itching, erythema, allergic reaction to ultraviolet rays, etc.

[0010] In addition, cosmetics containing UV blockers, moisturizers, antioxidants, etc. are widely used to prevent wrinkles, but the actual wrinkle improvement effect of these products is very little
